T0 LLgWHOM IT MAY CONOERN: v v

Be it known that I, FRANKLIN RANsoM, ot the city of Buffalo, in the county of Erie, and State'of New York, have invented a certain new and improved Hydraulic Engine; and I do hereby declare .that the following is a full and exact description thereof, refercnc'ebeing had to the accompanying drawings, making part of this spcciiication, which represents a longitudinal vertical section of my improved machine.

'.lhc object of my invention is the construction of a. machine, to be operated by the pressure produced by the elevation ofthe fountain or supply above the locality ofthe machine, by which a portion of said water may be forced to a greater or less height above that of the fountain. Themachine is especially designed for cle- I voting water to the upper stories of buildings, although it may be employed for any ofthe various purposes for which it is adapted. I

The invention consists of ahydraulic engine, composed of a cylinder, piston, and valve, operating in a manner similar tc the common steam-engine, combined withl and operating a double-acting force-Dump, through the direct agency of a piston-rod, to which the pistons of both are attached.

v In the drawings, A represents the cylinder of thc hydraulic engine, vB a common slide-valve, c c the portslending to each end of the cylinder, and d the exhaust or escapepassage ofthe water employed in operating the engine; E, the piston attached to rod F, on the opposite end of which is secured the piston E of the pumpcylinder ,Gu The valve B ot" the engine may be operated by any suitable tripping-device, that shown being a lever or arm, H, weighted at 4the upper end, and pivoted et the lower end to the centre ofthe piston-rod, in such a manner as to allow. the upper end of the lever to oscillate in actuating the valve.

The valve-rodI is supported at its end, andslides in a standard or support, j. At the upper ends ot` two other standards', 7c lo", are hinged two otherlevers, Zl/v, against the upper ends of which the lever H strikes, as it preponderates in either direction. .lo the valve-rod, at proper positions, are adjusted collars, man', fastened by thumb-screws, or equivalent, against which collars the lower ends of levers, ZZ', press in actuating the valve. N represents thc supply-pipe, which 'conducts the water, from the fountain or other elevated source, to the pump and engine, 0 being the pipe leading to the valve-chest, and j: a branch-pipe communicating with the two pipes g q', that open into the'ends of th'e pump-cylinder. These pipes arc provided with the ordinary hall or' flap-valves a r', to prevent the reflux otithelwater.

From the pump at each end the water 'is forced through pipes, es', and check-valves t t', into the elevatingpipe-u, through which it is 4forced to the required height. l

The operation of my improved machine is as follows, t The valve *being at one of its extremes, as shown, the water under the pressure caused by the elevation of the fountain is. forced, through port c, into the endof the cylinder, where, pressing against the piston, it drives it towards the opposite end of the cylinder., As the piston E begins to movc, t causes a corresponding movement of the pump-piston, the increased pressure of. which against the water in the pump causes the valve r to close, while the water inf) 'g' is forced by thesuperincumbent column, due to the common fountain, against the piston E of thepump, causing the said piston to force the water'in the pump through the pipe s and valvef, and up the pipe u, by the combined pressure of the column of water against the pistons of both pump and engine. 'This movement ofthe piston-rod carries the lever H, at the inclination shown, till its lower extremity comes in contact with 'the stuing-box of the pump, which. causes the lever to pass the vertical, and preponderetc in the other direction.

leve;` H inelining to the position shown in red lines,- comes in'contact with the short arm of lever `Z, the. long arm of which being in contact with collar m, slides the rod and valve to the 'other extreme, closing the'port c. The water now being permitted to enter port c, starts the piston towards. the other end ofthe cylinder, the v water therein escaping through' the exhaust into pipe d, which leads to the rooms in the lower stories, or other point where its use may be required. v

This reverse movement of the pump-pistcntcauses valve rf to close, when the water ilowing through qv pressiss against the piston, which is thus` again driven bythe conjoint `action reultingfrom the pressure of the columns on the two pistons.

It is evident. that the waterwpuld lrise in pipe u toa height equal to 'that of thelfount'ain, in accordance with the law of equilibrium, Without the aid of the engine. It is equallyobvious that iihateverforee is 'transf l ferred from the engine to the -piston of the pnmp,'will he utilized 'in elevating the water in pipe u above the level of 'the fountain o r supply. A n

l The larger' the piston of the engine, compared with that of the pump, the greetenwill bethe height to whichthe water in u canbe forced. If the pistons f the'pnmp and enginenre f the same size, it-is evident that the Water can be elevatedto a height equal to twice thatf the fountain above the machine, not considering the friction in the pipes and machine, which'would diminish the result somewhat. By increasing thel relative'siie of the pistono the engine, the'water in pipe u may be forced proportionally higher, as `experiment hasfnlly demonstrated.

` Y' In most cities and towns, where vater 's supplied to the hnildings by means otpipes,l tlie `s oureeof snpplji is usually suciently elevated for the water, in seeking an equilibrium, to rise to about they middle stories, 'while the 'water that'is requiredi forA the upper floors has Vto-heleal-r-ied 11p-by hanl.y i By the use of my improved machine, the'quantity requiredhfor the upper 4stories can be readily elevated, withont the Waste *other machines,

occasion, as the exhaust or waterA discharged from the engine is conduet'ed,z by pipe d, to the "ario'us' points on the lowerl-iloors and'baseme'ntgwhere' its use is required.

v `the manner'and for the pnrpose'sxbstantially as set-forth.'

pleasure, so as to pump e. greater or less quantity, as required, acordingas the'stop-eoek is turned.

` By closing the' same, so as 4to preventthe escape, the Tmnchineis immediately stopped, Whenever water ia- `drawn frein piped, in upplying the lower floors, a p foportional quantity willv beelevated. to. the upper stories; the relative amount thatwillfbe supplied to the dierent doers being regulated hyltherelative sizes' cf tho two` pistons,whieh are constructedaccordingly. 4 4 f What I claimfa's my'invention, isfs -The4 engine A and pump G, connected to the 'supply-pipe N, hy the b ranehesfo and p, so as to operate in lhe pipe d being 4provided with a stop-cock, W,'enahles the operation of 'the machine to he controlled at .4 FRANKLIN RANSOM.
